DOOR-CALENDAR.

SPECIFICATION forming part of Letters Patent No. 699,837, dated May 13, 1902.

Application led December 30,1901. Serial No. 87,651. (No model.)

To all w'wm it may concern:

Be it known that I, GILBERT W. EDMOND- SON, Aa citizen of the United States, residing at Champaign, in the county of Champaign and State of Illinois, have invented new and useful Improvements in Door-Calendars, of which the following is a specification.

My invention relates to a calendar or indicator designed to be placed either permanently or temporarily on office-doors or in similar situations,whereby and whereon signs and messages or instructions may be placed, to be read by whomsoever may be interested, the object being to provide an appliance or device of this character which may always be convenient and by which various signs may be shown and the same quickly changed, so as to display any one of a number that may be desired. This and other objects not hereinbefore mentioned are attained in the invention illustrated in the accompanying drawings, forming part of this specification, in which similar reference characters in the several iigures thereof indicate like parts.

Referring to the drawings, Figure l is a front elevation of a calendar constructed substantially in accordance with my invention; Fig. 2, a side elevation thereof; Fig. 3, a vertical central sectional view thereof; Fig. 4, a fragmentary end View of the sign-cylinder; Fig. 5, a fragmentary sectional view showing parts of the time-indicator; Fig. 6, a rear elevation of a supporting-stand for the cylinder, showing a spring-stop attached thereto; Fig. 7, a fragmentary sectional view of portions of the cylinder and case and a stand, as on a line l l in Fig. 6; and Fig. 8, a central longitudinal sectional view of the cylinder-case, showing the cylinder therein in elevation.

In constructionI employ a frame A of suitable form, which is designed to be placed against a door or a wall in a vertical position, a suitable hanger a being attached to the top of the frame for hangingit, and also the frame may be screwed or nailed to a door. The exposed parts of the frame maybe variously formed for ornamental purposes, if desired.

Sign boards or plates B and C are placed one below the other at the top of the frame A. These preferably comprise glass plates attached by means of screws to the frame,

and it is designed that the name of the occupant of the office be placed behind the upper plate B and any suitable sign behind the lower plate 0suchas Will be in about The lettering may be painted either on the glass or on the frame, as Will be obvious.

Below the sign-board C is a dial D in a case b, provided with a pointer or indicator E, the dial and the pointer being covered by a glass plate F, secured to the case by a band d. The pointer E is secured to and supported by a hub G, rotatively mounted on a stud@ and adapted to be engaged by a clock-key H, the plate F having an aperture f, through which the key may be inserted to engage the hub. The dial is suitably laid oif and marked similarly to a clock-dial, except that at the top, where the hour 12 is usually indicated, a zero-mark h is placed, and the twelve hours are indicated otherwise in afamiliar manner, the l being at the right and the l2 at the left side of the zero-mark. Below the dial is a case I, in which is mounted a rotative cylinder K, securedV to an axle or shaft L. The case-,front has an aperture covered by a glass plate J. The cylinder preferably comprises two heads at the ends thereof and a series of card-holders t', extending longitudinally and secured to the heads. The holders are preferably composed of strips of thin metal bent over at their edges, so as to form channels in which the sign-cards M may be inserted, the cards having suitable inscriptions indicating the place at which the person sought may be found. Suitable stands N are secured in the case I and support the shaft L, theI latter having a squared end j, adapted to be engaged by a clock-key Il through an aperture in the end of the caso I. An escutcheon 7c may be employed if the end j extend through the case.

An annular plate O, having indentations or recesses l, is secured to a cylinder-head, and a spring-stop P, having a projection p, is secured to the adjacent stand N and so arranged that the projection may engage the indentations or recesses when the cylinder is rotated, the engagement being such, however, as to permit of forcible movement of the cylinder.

A slate Q is attached to the frame A below the case I, on which callers may Write mesa sicians oice and there being no attendant inthe oiice to receive visitors, if the physician be in his office he may, by means of a suitable key, (such as an ordinary clock-key, if so designed,) set the pointer E, as shown, at the neutral point h. Should he leave the office, he may set the pointer so as to indicate any hour at which he may expect to return, and he may also rotate and set the sign-cylinder so that any desired sign may be read at the glass J through the opening in the front of the case I. After having set the pointer and the cylinder the key is of course withdrawn, so that meddlesome persons cannot interfere with the devices. A caller may then read that the physician will be in at about a certain time and that he may at once be found vat his residence or at such other place as a card M may indicate, each card having a different and suitable sign thereon.

Having thus described my invention, what I claim, and desire to secure by Letters Patl. In a door-calendar, the combination of the frame, the removable sign-plates, the dialcase situated below said plates and projecting forward of the plane thereof, the apertured plate covering said dial and the edges of said case, the band securing said plate to said case, the pointer, the pointerhub in range of the aperture in said plate, the zero or neutral mark fixed perpendicularly above said hub, the sign-case projecting from the frame below and beyond said dial, the shaftstands mounted in said case, the spring-stop attached to the inner side of one of said stands, the cylinder-shaft in said stands, the cylinder-heads secured to said shaft, the annular plate having the recesses therein and secured to the outer side of one of said heads in contact with said stop, the card-holders attached to said heads, the cards in said holders, and the slate secured to said frame and extending from the rear underside of said sign-case, substantially as shown and described.

2. In a door-calendar, the combination of the frame, the pair of removable sign-plates extending across the upper end of said frame, the dial-case projecting from said frame immediately below said plates, the zero-mark fixed below the center of the lower one of said plates, the pointer, the apertured glass plate, the retaining-band, the sign-case attached to said frame adjacent to said dial-case, the glass plate at the front of said sign-case, the escutcheon at the end of said sign-case, the

cylinder-stands mounted in said sign-case,

the spring-stop secured at the inner side of one of said stands, the shaft mounted in said stands with the squared end thereof adjacent to said escutcheon, the cylinder-heads secured to said shaft, one of which is adjacent to said stop, the annular plate having the depressions j GILBERT W. EDMONDSON.
